我正在尝试使用<select>，以便在更改时隐藏/显示div。
我想使用twitter bootstrap collapse插件。
我有一半使用此示例http://plnkr.co/edit/9lPe61?p=preview
但是当您向选择中添加selected时，它会破坏所有内容：http://plnkr.co/edit/w9XW8R?p=preview
<div class="accordion" id="accordion" >
<div class="accordion-group">
<select class="accordion-toggle">
<option value="1" data-toggle="collapse" data-parent="#accordion" data-target="#collapseOne">1</option>
<option value="2" data-toggle="collapse" data-parent="#accordion" data-target="#collapseTwo">2</option>
<option value="3" data-toggle="collapse" data-parent="#accordion" data-target="#collapseThree">3</option>
</select>
<div id="collapseOne" class=" collapse in">
<div class="accordion-inner">

JS - 我想我需要添加到插件中以检查是否有selected="selected"以便它也适用于选择，但我无法弄清楚这需要去哪里？

OP，
我认为http://plnkr.co/edit/qfB8Uf?p=preview就是你所追求的。
...
$('document').ready(function () {
$(".accordion-dropdpwn").on('change', function (e) {
var selected_value = $(this).val(),
$target_elem = $('a[href="' + selected_value + '"]');
$target_elem.trigger('click');
});
$('.accordion-toggle').on('click', function () {
var selected_value = $(this).attr('href');
$(".accordion-dropdown option").removeAttr('selected');
$('option[value="' + selected_value + '"]').attr('selected', 'selected');
});
$(".accordion-dropdown").trigger('change');
});
...
由于change的{{1}}事件会返回所选<select>（孩子）的value，因此我填写了对手风琴option的引用用户更改下拉列表时应该受到影响。
一旦我们获得了参考，我们只需触发该项目的点击事件。另一个重要的一点是确保在加载页面时，手风琴将反映<a>的当前状态 - 即select option将打开/激活的任何一个状态。
最后，还有双向控制。由于如果用户更改了selected="selected"，手风琴会发生变化，预计单击手风琴会改变<select>。
希望这有帮助。
